Title: Electronic exchange system
Inventor: EBISAWA YOSHIZO
IPC: H04M15/00
Filed: 1995-05-23
Abstract: PURPOSE: To attain dialing utilizing properly a measured rate system and a fixed charge system. CONSTITUTION: An expected speech charge in the measured rate system or the fixed charge system is calculated for this call and when the specific trunk is lower, a central controller 9 controls a trunk circuit 6a and the specific trunk (trunk line La) is used for the call. When the fixed trunk (trunk line Lb) is lower, the expected speech time of this cat is added to an accumulated speech time to calculate a new accumulated speech tie. When the charge is independent of a succeeding charge stage, the central controller 9 controls the trunk circuit 6b and the fixed trunk (trunk line Lb) is used for the call.  When the accumulated speech time reaches the succeeding speech charge stage, a virtual accumulated speech time being the expected accumulated speech time up to a closing date in a month is calculated and when the succeeding speech charge stage is reached, a new speech charge stage is used for the call and the call by the same virtual accumulated speech charge is increased to reduce the amount. When the new speech charge stage is not set, the call for the connected fixed trunk is stopped by the control of the central controller 9.

Title: Manufacturing of printed wiring board
Inventor: NISHIYAMA TOSAKU
IPC: B23B35/00
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To keep the surface roughness in a good condition, by supplying the liquefied gas to a hole working part of a printed wiring board to perform the hole working while cooling the printed wiring board. SOLUTION: A drill 1 is attached to a drill chuck 3, and the working is performed while cooling the drill 1 by a liquid nitrogen 5 from a nozzle 4, so that the temperature around the working area is lowered when the hole working is performed to a base 2. By directly cooling the drill 1, the temperature of the drill 1 is not increased. The base 2 can be optionally cooled by the liquid nitrogen 5, and a metallic table suporting the base 2 can be optionally cooled by the liquefied gas 5. Thereby the attachment of the melted resin of the base 2 to the cutting edge of the drill 1 can be prevented, and the surface roughness of the inner wall of the hole can be kept in the good condition.

Title: Air volume control device
Inventor: TANAKA HISAYOSHI
IPC: F23N3/02
Filed: 1992-05-15
Abstract: PURPOSE:To enable an inverter control and a damper control to be automatically changed over by a method wherein an inputting of control of the inverter or an inputting of control of the damper is controlled to be selected. CONSTITUTION:A control part 17 causes an inverter 7 to output a constant control signal to a selector 13 during its normal operation and further causes a selector 15 to output a signal from an adder 4 when a trouble signal is received from the inverter 7. After this operation, the control part 17 causes an output from the adder 8 to be outputted and when it receives a return signal from the inverter 7, it causes the selector 15 to output a signal from the adder 8 and changes over to a signal from the adder 4 and then it causes the selector 13 to output a constant control signal. With such an arrangement, in the case that the inverter 7 is in a troubled state, a damper 11 can be changed over automatically to its control without deteriorating a controlling characteristics and when the inverter 7 is returned back to its original state, the inverter 7 can be changed over to its control without deteriorating a controlling characteristics.

Title: Rod driving device for reciprocating pump
Inventor: TOTANI SHIGENOBU
IPC: F04B9/04
Filed: 1981-08-06
Abstract: PURPOSE:To aim at smoothness in feeding fluid, by contracting a spring resiliently reacting to an abnormal pressure rise when pressure at the discharge side rises unusually, while decreasing reciprocating stokes by a rod in an automated manner. CONSTITUTION:When abnormal high pressure happens on the side of a discharge opening 6 for some reason or other whereby internal pressure of a pump  casing 1 is abnormally intensified, a spring 36 succumbs to the abnormal pressure as the rod 11 goes forward so that resilient contraction in accord with suchlike pressure is produced. As a result, such drive that automatically contracts  the stroke of the rod 11 is also produced, decreasing a capacity of expansion  and contraction of the pump casing 1, and feeds fluid little by little or eventually almost nothing so that any damage resulting from the abnormal pressure  is obviated. Like this, when abnormal pressure occurs in a reciprocating pump,  the stroke of the rod 11 is lessened at once and it can cope with the abnormal  pressure.

Title: Information reader
Inventor: TAKEDA MASAHIRO
IPC: G11B7/00
Filed: 1987-05-20
Abstract: PURPOSE:To read information as normal information if this information itself has no error, by compensating a part, where a first condition is satisfied, of information stored in a first memory means with corresponding information stored in a second memory means. CONSTITUTION:The first condition and a second condition easier than the first condition are set in a control part 3, and information which satisfies the first condition is stored in the first memory DB1, and information which does not satisfy the first condition but satisfies the second condition easier than the first condition is stored in the second memory DB2. A part where the first condition is not satisfied of information stored in the first memory DB1 is compensated with corresponding information stored in the second memory DB2. Consequently, information on a track is read even if information does not satisfy another condition though said information is normal information. Thus, the information read efficiency is improved.
